Don't we have a filename filter for x11?

[Slava Chigrin, 2014/12/16 13:32:34]

As far as I understand, file name filter for GN is set up here
https://code.google.com/p/chromium/codesearch#chromium/src/build/config/BUILD...
, during sources_assignment_filter  setup. Seems, there are no filters, relevant
to x11 in file names. And comment there forbids adding more filters.
